Note: The vehicles will be delivered to their corresponding garages when they are unlocked. You cannot modify any special or pre-customized vehicles. There is also a storage limit for garages that may prevent unlocked vehicles from appearing there.

Note: The weapons will appear in your weapons cache. To get infinite ammunition, pick up, unlock, or buy a weapon once. The weapon must be in the cache to get unlimited ammunition. Toggle to it when entering the cache.

Fly far off the west coast of the prison to find five secret islands. Their names are "Bone", "Lookout", "Ruins", "Ship Wreck", and "Super Secret".

Hidden Easter Bunny

Follow the arrows that start on Ruins Island. Ruins Island is close to Super Secret Island, with the Volution Easter Egg on it. Ruins Island has an arrow that points to Lookout Island, then to a small unnamed island, then to another small island with an "X" on it. Get on it, and you will be teleported to a ring of arrows pointing to a floating Easter Bunny.

Easy money

Find and store a few armored trucks in your garage. When they are destroyed, they will respawn in your garage again. Blow a truck up, and you should get a decent amount of money. After collecting the money, go back to your garage, and get the truck again. It may cost $600 for repairs, but you should get at least $1,000 for destroying one.

Easy Snatch activities

Use a Bear (the Police APC) to easily complete Snatch activities. It is virtually impossible to stop once moving because it is nearly invulnerable. It can drive over smaller cars and pickups, the chaingun has infinite ammunition. It holds three passengers.

Easy kills in Zombie Uprising

Use the flaming zombies as a weapon. When they come after you, let them follow you. Run into big crowds of zombies so the flaming zombies set the other zombies on fire, which will then count as kills for you. Also, use headshots for the small zombies.

Entering vehicles faster

Stand on top of a vehicle and press Triangle. You will instantly be in the car.

Drive on walls

Use any motorcycle (Prototype recommended), and drive at a wall. At the correct moment, do a wheelie, and when both of the tires are on the wall, hold Up and hit the gas.

Taser execution

When you take a human shield, switch to your Taser and press L2. This will save some ammunition.

Blow-up doll

Go north from the lighthouse on the prison island. You will reach a large sewer pipe that has graffiti on the sides. Go into the pipe to find a blow-up doll on a very dirty mattress. Note: It will disappear after awhile.

Fishing

While on a dock, allow your character to remain idle for a short amount of time. He should walk up to the edge, take out a fishing rod, and begin to fish. He will continue to do so until you move him again.

Working out

While in the prison yard, allow your character to remain idle for a short amount of time. He should walk over to a location and start curling a pair of dumbbells. He will continue to do so until you move him again.

Have homies follow you in a different car

Get three homies, then find a car that only holds two people. Get in the car, and one of the homies will get in with you. If you wait, your other two homies will find a car and follow you. Note: This also works with motorcycles.

Defeating Akuji

To kill Akuji in the teahouse, use L2 to counter his attacks. It does damage and knocks him down. When he is down, stab him twice quickly before he gets up. Repeat this until he has been killed.

Defeating Maero

To defeat Maero the first time on top of his hideout, hit him once with an RPG. When scoring a direct hit, he will go on one knee and stay down. You can then shoot him until he is defeated. If he gets up, just shoot him again. To finish off Maero in the arena, use some of the rockets to blow up all the trucks except for his. Use extra rifle ammunition to shoot his Monster Truck.

Defeating Mr. Sunshine

To kill Mr. Sunshine in the factory, use a rocket on his voodoo doll to knock him down and cause damage. Hit the doll once to break his shield. You can then shoot him until he reaches the bottom floor. Note: If he completes his ritual with the voodoo doll, it will send you flying and inflict lots of damage.

Defeating The General

To kill The General in the mall, use the saved rockets to blow up his armored Bulldog, then shoot him with any gun until he dies. Note: Do this quickly before he runs away.

Defeating Veteran Child

To kill Veteran Child in his club, bring lots of ammunition. Use the stun grenades located around the pillars to separate him and Shaundi, then just run up and shoot him. Repeat this until he is dead.
